ImGui Integration in UltraEngine

While the integrated GUI-System is powerful and great, I decided to give ImGui a go. 

ImGui is an Intermediate GUI, which means you describe the layout in every frame and get what needs to be rendered, This is useful if you want to add some simple debug values to screen. If you look onto the webpage of ImGui you can see what can be done with it.

This is a screenshot  showing an early stage  of the prototype integration, to see if it is even possible.
